Abstract: Large Scale Renewable Energy integration into main grid has several challenges associated with it such as Frequency Control, Voltage Management, Load Imbalance etc. India as an emerging economy requires power as the basic need for development. The Government of India through the Jawaharlal Nehru National Solar Mission is promoting Solar Power in India and has set an ambitious target of deploying 1,00,000 MW by 2022. This target will comprise of 40 GW through Rooftop Solar and 60 GW through Large and Medium Grid Connected Solar Power Projects. The current Grid Interactive Renewable Power Scenario of India as on 31.03.2015 is:
The main objectives of this project are to understand the challenges present with integration of Large Scale Renewable into the Indian Grid and to find possible solutions by the study of Grid Codes of India, Sri Lanka, Denmark, Germany, Spain and USA (California). The study of Grid Codes of different countries including India has been performed in an order to understand the situation of grid connectivity through regulatory point of view. This analysis also includes study of Ancillary Services and Ancillary and Capacity Market. The Ancillary Services have been regarded as the services that are procured by a Transmission System Operator to stabilize power system and maintain power quality. For the study of Ancillary Services, the services that are used in Australia, Denmark, Germany, Spain and USA (California) have been studied. The Central Electricity RegulatoryCommission on 1st May 2015 came up with the Draft Regulations on Ancillary Services Operations. The regulation has also been studied upon and has been summarized in this thesis. As for the Ancillary Market which is a market mechanism developed for selling and purchasing of the Ancillary Services, the present markets in Germany, USA (California) and Western Australia have been examined. The Capacity Markets are set up to ensure supply in the hour of maximum need. These markets are devised to sell Capacity in terms of MW or kW. The energy is auctioned off a few years prior to when it actually needs to be delivered. Capacity Markets that are prevailing in Western Australia and United Kingdom have been studied. This thesis also includes the Capacity Market discussion presently going on in Germany. The entire analysis is done with the view of finding out the plausible causes that may impact the large scale grid integration of renewable energy into Indian grid. The aim through this analysis is to understand how the challenges can be overcome through the application of different measures such as introduction of Ancillary Services and Ancillary and Capacity Markets.
